Definitions

  • This invention relates to an electrical terminal connection formed of two generally identical parts.
  • Conventional electrical connections are typically comprised of a male blade terminal and a female receptacle terminal. An electrical connection is made when the blade terminal is inserted into the receptacle terminal.
  • One shortcoming of conventional electrical connections is that the blade terminal and the receptacle terminal each require separate design, tooling, and inventor.' costs. Further, the known male/female terminals do not ensure a large number of contact points, or contact area.
  • the present invention provides an electrical terminal connection made by interconnecting two generally identical terminals having U-shaped blades. Since both terminals may be identical, the disclosed invention reduces design, tooling, manufacturing, and inventory costs.
  • One embodiment of the inventive connection includes a terminal having a spring contact strip fixed within each U-shaped blade.
  • the spring contact strip has a plurality twisted contact louvers.
  • Another embodiment of the inventive connection includes a .?.
  • terminal having a U-shaped blade with corrugated sides. All of these embodiments reduce the engagement force necessary to mate terminals. More importantly, the non- planar sides ensure a larger contact area with a number of contact points.

Abstract

L'invention concerne une connexion électrique à bornes réalisée en connectant entre elles deux bornes identiques ayant de languettes en forme de U. Autrefois, les connexions électriques étaient réalisées de manière typique en insérant la languette dans la borne de logement. Dans une réalisation de l'invention il est prévu dans la connexion une borne avec une bride de contact à ressort ayant une pluralité d'écrans de contact torsadés au sein de chaque languette en forme de U. Une autre réalisation de l'invention prévoit une connexion comportant une borne présentant une languette en forme de U avec des parois ondulées. Les deux variantes augmentent la zone de contact tout en réduisant la force d'engagement requise pour accoupler les bornes.
